Product Introduction
The 31000-16-10-00-122-00-05 belongs to the Bently Nevada 31000 Series of proximity probe housings. This assembly provides mechanical and environmental protection for radially mounted 3300 XL 8mm probes used in vibration and Keyphasor measurements. Specifically, it allows technicians to adjust probe gap or replace the probe without disassembling the machine casing. Therefore, this housing reduces maintenance downtime for turbines, compressors, and large motors.
Technical Specifications
This housing assembly arrives configured with a 3300 XL 8mm probe and a 1.0 m (39 in) probe cable. The probe penetration depth measures 12.2 inches, which suits thick machine casings or insulated installations. Additionally, the mounting thread is a 7/8-14 UNF 2A type for secure installation. The assembly does not include a standoff adapter or conduit fittings in its standard configuration.
The housing body uses glass-reinforced polyphenylene sulfide (PPS) thermoplastic with conductive fibers. Meanwhile, the internal sleeve and retaining chain are made of AISI 304 stainless steel for corrosion resistance. The outer sleeve and exterior screws use AISI 303 stainless steel. Furthermore, the O-ring material is Neoprene for reliable sealing.
Mechanical and Environmental Parameters
The 31000-16-10-00-122-00-05 carries a Type 4X rating certified by CSA and an IP66 rating for dust and water ingress protection. It also meets CENELEC EN50014 standards for electrostatic dissipation in hazardous areas. The temperature rating spans from -51°C to +105°C (-60°F to +221°F), covering extreme operating conditions.
For impact strength, BASEEFA certified this housing to withstand two separate 4 Joule impacts at -39°C and at 115°C. Moreover, CSA verified samples to survive a 7 Joule impact at ambient room temperature. The recommended retaining nut torque is 29.4 N·m (260 in·lb). Finally, the typical weight is 1.2 kg.
Installation Guide
First, verify the machine casing thread matches the 7/8-14 UNF 2A mounting option. Next, insert the probe assembly through the housing and set the probe penetration to the required depth. Then, tighten the retaining nut to the specified torque of 29.4 N·m. After that, route the probe cable through the appropriate conduit or cable gland. Finally, connect the probe to the extension cable and monitoring system, then verify the gap voltage before startup.
